SPECIFICATION forming part of Letters Patent No. 538,907, dated May 7,1895.

Application filed April 27, 1894. Serial No. 509,172- (No model.)

My invention relates to improvements in.

butt pins and tips for attachment to ordinary butt knuckles, and theobjects of my improve ment are simplicity and economy in constructionand particularly to construct the ball portion of the tip of sheetmetal.

In the accompanying drawings, Figure l is a sectional view of a butt orhinge, together with my pin and tips applied thereto, the pin and tipscrews being in elevation. Fig.2 is a side elevation of the lower tip.Fig. 3 is a sectional view of a pin and tip in a somewhat modified form,and Fig. 4 is a corresponding view of the lower tip to accompany saidpin.

A A designate the leaves of a butt or hinge for which any ordinary formof butt or hinge may be substituted. 5 designates the pintle or pinhaving at its upper end a small shoulder 6 which is formed thereon in anupsetting or heading machine, and above said shoulder a tenon 7, theupper end of which is screw threaded. Upon this tenon 7, I place the tipbase 8 with its under side pressed against the shoulder 6 of the pin.The ball portion 9 of the tip is made hollow by striking it up from.

sheet metal and is threaded at its mouth or opening to fit the threadedend of the tenon 7, so that by screwing said ball portion of the tipfirmly upon the upper end of the pin, the tip is complete as shown. Thelower tip is constructed of the same two parts 8 and 9, but instead ofbeing fastened upon the pin 5 they are fastened upon the tip screw 10,one

end of which has a reduced tenon or neck 77 which is threaded on itsend, the tipbase being first placed thereon and resting against theshoulder formed at the junction of the screw 10 and tenon 7 7. The ballpart 9 of the tip is then screwed on to hold them in place as shown, thetip being screwed into the end knuckle of one of the leaves. This formis particularly desirable when the tip is to be made of brass or bronzemetal.

WVhere the tip base is on the pintle as at the upper part of Fig. 1, andin Fig. 3, that portion of the pintle which projects from the broad sideof said tip base is the shank of the tip which enters the knuckle and bymeans of which the tip is secured to the knuckle. Where the tip base ison the screw as at the lower part of Fig. 1, and as in Figs. 2 and 4that portion of said screw which projects from the broad side of saidtip base is the shank of the tip which enters the knuckle and by meansof which the tip is held in place.

Figs. 3 and 4 show a modification which is more particularly designedfor an iron or steel tip and in which the tip base 88 is formed directlyupon the end of the pin by means of anupsetting or heading machine andon the end of said tip base is a screw threaded tenon which receives theball portion 9 of the tip which is firmly screwed thereonas beforedescribed. In Fig. 4 the tip screw 100 is in like manner formed with thetip base 88 headed or upset thereon and provided with a like threadedtenon 70 upon which the ball portion 9 of the tip is firmly screwed.

I am aware that a prior patent shows and describes a hinge leaf having apintle socket 'or knuckle at each end with integral screw threadedshanks projecting therefrom, a pin tle extending through said knucklesand their shanks, and detachable caps, internally threaded, which capsare screwed upon the knuckle-shanks over the ends of the pintle, and thesame is hereby disclaimed.

By my improvements I divide the tip at its narrow neck into two parts,namely the base portion and a hollow ball portion, whereby I am enabledto cheaply construct these tips by striking up the ball portion fromsheet metal and finishing the tip in any manner desired, and toconstruct them separately from the butt leaves and knuckles so as to beapplicable to ordinary butt knuckles.

I claim as my invention 1. The herein described tip for attachment toordinary butt knuckles consisting of the attachable and detachable tipbase, a shank projecting from the broad side of said tip base forattaching it to the butt knuckle, a screw threaded tenon projecting fromthe smaller end of said tip base and the hollow sheet metal ball portionof the tip screwed upon said tenon, substantially as described and forthe purpose specified.

2. The herein described butt tip consisting of the combination of thescrew or pin one portion of which forms the shank by means of which thetip is secured to the butt knuckle,

a shoulder on said screw or pin at the outer IO end of said shank, ascrew threaded tenon projecting from said shoulder, the hollow sheet
